Product details
This easy to use, Ex nA and Ex tc certified tachometer can display speed in engineering units from a wide variety of pulse output sensors such as a proximity detector or switch contact. It can be installed in Zone 2 or 22 without the need for Zener barriers or galvanic isolators thus significantly reducing cost. International certification allows use worldwide.

To simplify maintenance, the instrument also contains a second display which can simultaneously show the run-time of the monitored machinery.

Accessories, include a display backlight, isolated dual alarms and an isolated 4/20mA output.

The instrument can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional charge. An optional Stainless Steel legend plate is also available which can be supplied laser engraved with customer specified tag and application information.
